Records from fishing boats highlight four areas showing unusual diversity in sharks, tuna, billfishes, and other big predators, says Boris Worm of the Institute for Marine Science in Kiel, Germany. Those “major hot spots” are in waters off the east coast of Florida, south of Hawaii, off the Great Barrier Reef, and near Australia’s Lord Howe Island, Worm and his colleagues report.
